ESI ESI C-Class ESI E-Class ESI S-Class ESI X-Class Feature Phones

Feature Phones
The nice thing about the ESI family of phone systems is that they allow the customer to use one of the ESI Feature Phones. Each phone is a great addition to any office décor, but they are much more than just a nice looking fixture. An ESI Feature Phone has a sealed membrane below the keys, making it virtually spill proof. And, with a sturdy four position base, it will fit on any desk or counter space, while still allowing the user to see the status of the display keys.
